Introduction: Guitar Hero Fret Buttons Mod
This is a mod that will make the fret buttons on your guitar hero controller firmer and more responsive. You get less of that clicking / rattling sound you get when you're playing fast, and it requires less downward pressure to fret a note.
You will need:
Guitar Hero controller
Size 10 Torx screwdriver
Small philips screwdriver
Large-ish flat screwdriver
Duct tape (I used black "Duck" tape)
"Blu-tack", or other poster adhesive putty (e.g. "white-tack")
This idea is not mine as people have done similar things before, but there is no instructable, or indeed any clear set of instructions that I could find. And I haven't found any examples of people doing it to a Guitar Hero 3 controller, although the principle is the same for other GH guitar versions.
This is my first instructable so please be kind :)
Step 1: Remove All Screws in the Guitar Neck
After removing the neck from the guitar body, remove all the screws from it (excluding the one holding on the strap button, unless you don't use it, and want to remove it - I have).
You will need a size 10 Torx screwdriver for this.
Step 2: Open Neck
Separate the two halves of the neck to reveal the inside, and set aside the back of the neck.
Step 3: Dismantle Fret Button Assembly
First, remove the two screws holding the brown circuit board down, using a small philips screwdriver. I had trouble with one of the screws as the head appeared to be quite worn (despite the controller being brand new) but it came out in the end.
Use a large-ish flat screwdriver to remove the circuit board. It is quite a tight fit on the plastic posts, but if you're careful you shouldn't damage the board.
Carefully lift the circuit board and set it aside. Be particularly careful not to trap or fold the ribbon cable at any point as it's quite delicate.
Remove the blue rubber pad from the buttons, and set it aside - this will reveal the fret buttons. You can now remove these too.
Step 4: Make Your Spacers
Start by sticking two pieces of duct tape together, adhesive sides facing each other. This is what the spacers are made out of.
Personally I found 2 layers of tape was perfect, but if you feel more is needed (or you are using tape of a different thickness) then use more or fewer layers. I would suggest 2 to start with - if 2 is too much (you'll be able to tell this after reassembling the guitar and playing with it) then I would suggest buying some thinner tape and using that.
Cut strips of the tape that are 1.5cm wide. Then cut these every 2cm until you get 5 pieces of tape that measure 1.5 x 2cm.
Lay each one on a button to make sure that you're cutting was accurate, and there are no overlaps - the spacer should fit completely on the button, with no overhangs. If so, the button's movement may be impaired.
Step 5: Attach the Spacers
Make 5 small balls of your blu-tack (or equivalent). Don't make these too big as too much will make the spacer's surface uneven - see the picture for an idea of size.
Roll one of the small balls of putty between your fingers to make a sausage shape, and press it along the center line and 2 holes in the plastic on the back of one of the fret buttons. Then attach a spacer to this, ensuring it is central to the button and not overlapping the sides at all.
Do this for all five buttons.
Step 6: Reassemble the Fret Button Assembly
Place the fret buttons back into the neck, in the correct order. The correct order (starting from the head of the guitar) is green, red, yellow, blue, orange.
Lay the blue rubber piece over the buttons, pressing it into place, and ensuring it is fitted correctly.
Line up the circuit board and gently press each end to get the plastic screw posts through the holes in the circuit board. Then put the screws you removed earlier back in.
Step 7: Add Tape on Back of Circuit Board
The plastic on the back half of the neck is supposed to sandwich the circuit board to stop it bending. Despite this, i found that if you press a button hard, the circuit board will still bend to some degree, causing the buttons to move in a bit more than they should.
So to make the buttons firmer still, add a length of duct tape (torn to a smaller width) to the back of the circuit board as seen in the picture. This seems to help quite a lot in my opinion.
Step 8: Put the Neck Back Together
Replace the rear half of the neck, ensuring that the ribbon cable doesn't get trapped between the screw posts. If it does you could damage the wires inside.
Put all 9 screws back in using the Torx screwdriver.
Step 9: Play!
Reattach the neck to the guitar, and test it to make sure everything works. If the movement is too restricted, use thinner tape. If you want to reduce movement more, then make more spacers, but using 3 layers of tape instead of 2.
Please leave a comment if you thought this was good, or anything I missed or should change.
I'm planning more instructibles of other mods to my controller. Check back soon!
Happy modding ;)
